The 26-year-old winger, who has spent the past two seasons at the Eredivisie outfit, has agreed a five-year deal to become Rafa Benitez’s first signing of the summer

Napoli has agreed a 9.5 million euro fee with PSV to complete the signing of winger Dries Mertens.

The Belgium international has been capped 19 times, and will become Rafael Benitez’s first signing since being appointed as the Partenopei boss.

The playmaker scored 16 goals and created a further 17 in the Eredivisie this season and is excited to take the next step in his career.

“Rafael Benitez wanted me really badly and that gives me a lot of confidence. And when people doubt me and say Serie A is different from the Eredivisie because I won’t play against any Dutch defenders, that is when I’ll be at my best,” he told De Telegraaf.
